great, thank you. Did you make the plate that the magnet attaches to go in to the water instead of 1/2" above?
Do you think that one of these is enough on the end of the tank? I was planning on doing one on each end but after looking at these, I discovered that I could buy 3 of them for about the same price as an mp60. So I wonder if 2 on the front, one in the middle of the back, and an mp60 in in each of the lower back corners could be more even flow than 4mp60 on the back and one xf350 on the front. It would be $700 cheaper, but also 30% less flow in the rear top of the tank. I've never had a Gyre so I can concept this thing all day long and still not really know what's going to happen.
